Additional file 4:

Identification of M. truncatula ESTs similar to putative expression products of orf1 and TPases coded by MtPH elements. Sequence of the whole element was used as query against M. truncatula EST database, hits in orf1 and TPase coding regions with E value lower than 1e-06 were scored. Nearly identical hits to orf1 and TPase of the MtPH-M-1 elements are marked red.

Alignment of MtPH-M-1-Ia and the ESTs corresponding to orf1 (CX532696) and TPase (AW686181). Predicted exons of the orf1 and TPase are highlighted yellow and green, respectively, TSDs of the element are marked gray.
